I’m looking for a simple (simplest if possible) way of backing up and restoring a database.
I want to do a backup in one state and then after doing some operations get back to the backed up state.
Tried Database->Tasks->Back Up… and then Database->Tasks->Restore but I always get an error with:
Restore failed for...DBName
The tail of the log for the database "database name" has not been backed up...
So, I want to back up and restore with one simple operation each, can one advise me
to a solution, be it GUI or not GUI based?
It looks like you have Differential Backups set up. It is slightly more complicated than restoring a Full backup.

By doing a Full backup, you are going to break the chain of backups that the DBA set up, so it would be a good idea to check first with the DBA before you break his backup set.
Edited for very helpful comments:
You should use the COPY_ONLY option when you do a backup so that you do not break the chain of backups.
